Wiring

Common Connections:

• Potentiometer Sensor Module

  • OUT: Connect to A0 on the Arduino.

  • GND: Connect to GND on the Arduino.

  • VCC: Connect to 5V on the Arduino.

Writing the Code

Note

• You can copy this code into Arduino IDE.

• Don’t forget to select the board(Arduino UNO R4 Minima/WIFI) and the correct port before clicking the Upload button.

// Define the pin used for the potentiometer
const int sensorPin = A0;

void setup() {
  Serial.begin(9600);  // Initialize serial communication
}

void loop() {
  // Read and print analog value
  Serial.println(analogRead(sensorPin));
  delay(50);
}
